Definitions

  • the invention relates to a structure for a vehicle seat, which structure comprises rigid structure components which form cavities and comprises a foam structure which at least partially fills the cavities.
  • Such vehicle seats are generally known.
  • the German laid-open specification DE 102 14 476 A1 and the German laid-open specification DE 103 21 289 A1 respectively disclose a frame composed of hollow profiles and a backrest of a vehicle seat, with a foam being arranged in each case in cavities of structural elements.
  • the German laid-open specification DE 10 2004 043 860 A1 and the German laid-open specification DE 197 46 164 A1 respectively disclose a backrest for a seat and a material combination having a profile which is hollow at least in sections, with a foam being arranged in cavities of structural elements.
  • German laid-open specification DE 42 08 150 A1 and the German laid-open specification DE 197 27 907 A1 respectively disclose a backrest for a vehicle seat and a method for filling cavities in workpieces or semi-finished parts.
  • German patent document DE 40 28 895 C1 and the European patent application EP 1 591 224 A1 respectively disclose a foam body for partitioning body cavities and a device and method for noise damping in cavities of vehicles.
  • the patent DE 10 2006 014 538 B3 discloses the arrangement of a cable in the interior of a tube on a motor vehicle seat, and an elastic body for a line bushing is known from document DE 198 17279 A1.
  • document DE 36 36 113 A1 discloses a method for forming a foamed mass in a cavity
  • DE patent 23 03 289 discloses a vehicle seat having a shell which supports a seat back pad
  • document DE 37 14 588 A1 discloses a safety seat back beam composed of plastic.
  • the object of the present invention is therefore the targeted formation or introduction of a filling in or into a cavity of a structural element of a vehicle seat in order to improve the mechanical properties of the vehicle seat, with a very cost-effective assembly process being sought in particular.
  • the object is achieved by means of a vehicle seat having a backrest and having a seat part, with the backrest or the seat part having at least one structural element which has a cavity, with the cavity being formed by a base plate and at least two profiles which are cohesively connected to the base plate, with a corner region of two profiles having provided in it a filling which is introduced to influence the stability and/or the deformation behavior of the backrest and/or of the seat part, with the filling having a foam support and a foam material, with the foam material at least partially surrounding the foam support, and the foam material preferably completely surrounding the foam support.
  • an improvement in the mechanical properties of the vehicle seat can be obtained in a simple manner in that the filling is arranged and formed such that, during the formation of the foam from the foam material (that is to say during the expansion of the foam material), firstly a good connection, in particular adhesive connection, with the inner surfaces or the inner wall of the structural element is obtained, and such that, secondly, easy insertion of the filling into the cavity is ensured, which leads to ease of assembly of the vehicle seat according to the invention.
  • the foam material is provided so as to expand during the drying process after the painting process (for example in a drying kiln) or that the foam material expands during a temperature step (for example in a kiln) without a painting step.
  • the foam reinforcement of the vehicle seat can be integrated quickly and in a simple manner in terms of assembly by means of one working step which is carried out in any case.
  • the structural element prefferably has a corner pressed part in the corner region of second profiles. In this way, it is possible according to the invention to obtain a targeted reinforcement at highly loaded points of the vehicle seat or of the backrest and/or of the seat part.
  • FIG. 1 schematically shows, as an example of a structural element, a seat back structure or a seat back segment of, for example, a split foldable backrest.
  • FIGS. 2 and 3 show schematic illustrations of a vehicle seat according to the invention, conforming with all of the embodiments.
  • FIG. 1 schematically illustrates, as an example of a structural element of a vehicle seat, the rear view of a seat back segment 1 of a backrest.
  • the seat back segment 1 or the seat back structure 1 (the figure shows only a seat back segment 1 of, for example, a split foldable backrest) comprises a base plate 2 and four U-shaped profiles 3 . 1 to 3 . 4 which are placed thereon and which, together with the base plate 2 and preferably the corner pressed parts 4 placed thereon, a rectangular frame with an encircling hollow chamber 5 .
  • the base plate 2 and the profiles 3 . 1 to 3 . 4 are composed substantially of for example metal, in particular steel or aluminum sheet, or substantially of plastic, for example glass-fiber-reinforced plastic.
  • the profiles 3 . 1 to 3 . 4 are connected to the base plate 2 for example by welding or adhesive bonding.
  • the connection and/or stiffening of the profiles 3 . 1 to 3 . 4 with one another or with the corner pressed parts 4 takes place according to the invention (if appropriate in addition to the welding or adhesive bonding) by means of a foam structure 6 introduced in angular form into the hollow chamber 5 in the corner regions.
  • Said foam structure 6 stiffens the corner region by means of its inherent stiffness and/or by locally adhesively bonding the profiles 3 . 1 to 3 . 4 to one another and to the base plate 2 and/or to the corner pressed part 4 .
  • the corner pressed parts 4 it is also possible according to the invention for the corner pressed parts 4 to be dispensed with entirely and for the increased stability requirements in the corner region, or the higher material stresses to be absorbed by the material, to be accommodated solely by means of the profiles 3 . 1 to 3 . 4 and the foam structure 6 . In this way, it is advantageously possible according to the invention to dispense with the weight and the installation space for the corner pressed parts 4 .
  • the introduction of the foam structure 6 may take place by inserting a finished foam part, which is shaped correspondingly to the hollow chamber 5 , before or during the welding of base plate 3 and profiles 3 . 1 to 3 . 4 .
  • the foam structure 6 is first introduced after the welding process by means of an injection of a foamable mass into the hollow chamber 5 .
  • Particularly preferable is the insertion of an in particular strand-like foam precursor, which has a three-dimensional shape, into the hollow chamber 5 , which foam precursor is inserted into the hollow chamber 5 before, during or after the welding process and foams to form the foam structure 6 after an activation.
  • the activation may take place for example as a result of a supply of heat during the painting of the seat back structure 1 .
  • use is preferably made of rigidly cross-linking foam systems, for example based on epoxide.
  • the seat back structure 1 is hereby on the one hand stiffened in the region which is highly loaded in the event of an accident, and on the other hand, an additional welding of the profiles 3 . 1 to 3 . 4 to one another may be dispensed with if required.
  • FIGS. 2 and 3 show a vehicle seat according to the invention.
  • a vehicle seat of said type comprises a seat part 12 and a backrest 13 .
  • Both the seat part 12 and also the backrest 13 have in each case at least one structural element 14 which, in the context of the present invention, is configured in the form of the base plate 2 and the profiles 3 . 1 to 3 . 4 or else in the form of the base plate 2 , the profiles 3 . 1 to 3 . 4 and the corner pressed parts.
  • a cavity 15 is provided at least in partial regions in said structural element 14 , which cavity 15 is also referred to in the context of the present invention as a hollow chamber 5 .
  • the cavity 15 is for example in the form of a frame substantially following the outer shape or periphery of the backrest 13 or of the seat part 12 , and is substantially angular, rectangular, triangular or angled in cross section. According to the present invention, at least one partial region of the cavity 15 , and preferably also only one partial region of the cavity 15 , has arranged in it a filling 16 which comprises a foam material 18 .
  • the filling 16 or the foam material 18 is also referred to below as a foam structure.
  • the filling 16 or the foam material 18 may duly be injected from the outside by injecting an easily deformable or foaming material (for example through an opening in the cavity 15 ), but it is preferable according to the present invention for the filling 16 to be introduced into the cavity 15 in the form of a still-unexpanded and substantially hard, or at any rate substantially non-adhesive, foam material 18 which is connected to the foam support 17 , or else fastened to or positioned on a structure part which forms a cavity wall, with the cavity 15 then being formed by means of a connection to another structure part.
  • the foam material 18 is then expanded, as a result of which the foam material 18 then at least partially or preferably completely surrounds the foam support 17 . To illustrate this, FIG.
  • FIG. 3 shows a detail of a cavity 15 formed in the structural element 14 , with the filling 16 , that is to say the foam support 17 and the foam material 18 , being illustrated in the cavity 15 in the unexpanded state of the foam material 18 by means of solid lines, and with dashed lines or dots illustrating the limit of the foam material 18 in the foamed state.
  • the expansion of the foam material 18 may take place in particular by means of a KTL bath treatment (not illustrated).
  • a KTL bath treatment (not illustrated).
  • This is to be understood to mean a treatment in an electrocoating kiln or a cathodic dip coating process in which the structural elements 14 of the vehicle seat are raised to a temperature of for example approximately 160° to approximately 180° over for example approximately 5 minutes to approximately 15 minutes, preferably approximately 10 minutes.
